Description

No other code in Twisted uses this method and it hasn't been touched in 6 years;

"""Gets rid of unsightly lefthand docstring whitespace residue.
You'd think someone would have done this already, but apparently
not in 1.5.2.
BUT since we're all using Python 2.1 now, use L{inspect.getdoc}
instead. I{This function should go away soon.}
"""

In regards to changing the docstringLStrip docstring, I think it should be left as is - it dates the method. Also, since it's going to be removed anyway, we probably shouldn't give the impression that we are still maintaining/modifying that method by updating the docstring.
